This method is on par with the No-Sand Method in terms of quality of finish but is a slightly slower process. However, it is faster than hand-sanding or using a Dremel to post process your prints. Relevant PPE such as a mask and gloves should be used when utilising this method.
- High-cover aerosol paint + primer (such as Rustoleum 2X)
- Acrylic or enamel fast-drying spray putty (such as Superfine High Build Filler)
- Isopropyl wipes or similar to clean parts
- 1.Ensure that your printed parts are clean and dry, wipe the parts down with Isopropyl wipes or a similar product and let dry.
- 2.Begin by applying a thin coat of high-cover spray-putty to the parts. Note that the spray-putty may cause blotching to your surface if applied too thick or unevenly across your surface.
- 3.Wait 30-45 minutes (or as instructed on bottle) between coats.
- 4.Re-coat your parts a total of 3-5 times.
- 5.Once you have applied all the necessary coats (according to how smooth you would like the finish of your surface) leave your parts to dry overnight. The spray-putty will fill up the gaps between the prints' layers and level your surface smoothly.
- 6.Apply a medium coat of high-cover spray paint to your part.
- 7.Wait 10 minutes between applying your paint coats.
- 8.Repeat the painting process 3-5 times as necessary.
- 9.Wipe your parts clean and you are ready to go.
